General description

Ethyl 3-hydroxybutyrate is one of the main aroma components of wine. It occurs naturally in fruits such as pineapple, tamarillo fruit, caja fruit and naranjilla fruit.

Application


  • Deciphering the immobilization of lipases on hydrophobic wrinkled silica nanoparticles.: This study explores the immobilization of lipases on hydrophobic wrinkled silica nanoparticles, highlighting the potential of these nanoparticles in biocatalysis applications, which can be critical for biochemical synthesis processes involving compounds like Ethyl 3-hydroxybutyrate. (Pota et al., 2024).

  • Exploring the Therapeutic Potential of Ethyl 3-Hydroxybutyrate in Alleviating Skeletal Muscle Wasting in Cancer Cachexia.: This research investigates the therapeutic effects of Ethyl 3-hydroxybutyrate in reducing muscle wasting in cancer patients, demonstrating its potential biochemical applications in medical treatments. (Zhou et al., 2023).

  • High-Pressure Depolymerization of Poly(lactic acid) (PLA) and Poly(3-hydroxybutyrate) (PHB) Using Bio-Based Solvents: A Way to Produce Alkyl Esters Which Can Be Modified to Polymerizable Monomers.: This study explores the depolymerization of biopolymers using bio-based solvents, resulting in alkyl esters like Ethyl 3-hydroxybutyrate, highlighting its applications in sustainable biochemical processes. (Jašek et al., 2022).
